Supertech Performance MAIVN-2304F Mazda / Ford Duratec 2.0 /2.3Lts. Intake Valve 36 x5.48 x 103.40mm /SS/ Blk. Nitrided/ + 1mm /Flat/Undercut/Backcut

Supertech valves are the best on the market, made from one piece of forged stainless steel for the ultimate in strength and durability. Supertech valves go through a special heat treatment process that obtains the right amount of harness for each engine to ensure the ultimate valve for your performance motor. Supertech offers their valves in either chrome coating, used in high performance valves, or hardened black nitrided which is most popular in European and Japanese motors.

Supertech High Performance Race Engine Valves features:

  • The microhardness is higher than the stainless steel base material, keeping good ductility beneath the hard nitrided layer (microhardness is 800HV minimum)
  • Surface finish is smoother than with chromed stems, having less friction between stem and guide.
  • Valve seat surface is harder with the nitrided layer, lasting longer with lead free fuels, alcohols, nitro or other "explosive" mixes. Matches any kind of seats (nodular iron seats, steel powder metal seats, hard aluminum-copper seats or beryllium copper seats).
  • Higher rpm's engines take full advantage of all previous features. The higher the engine speed the bigger the power loss due to internal engine friction! The black nitride layer reduces this power loss due to less valve-guide friction.
  • The nitrided layer is adhered to the base material at a microscopic level, so does not"flake" or brake when the valves bend due to impacts with the pistons.
  • The Black Nitride applies to the whole valve while the chrome coating is only applied to the stem.

Nice shirt but size up one to two sizes.
Size: Large, Color: Clay
I love this shirt. it is good quality. I got the clay colored one. I really like it. They do run small. I normally wear a medium. So I got a large. It fits pretty well. It is a tad bit tight, but I am losing weight(145LBS) So far. So it should fit fine in a few weeks. I am 5,2 135Lbs. I probably should have gotten the XL.

Slim fit for the winner
Size: Medium, Color: Clay Floral Print
Beautiful orange shirt and I love the metal buttons. Very comfortable and I like the slim fit. It appears more tailored. I'm a tall guy at 6'4" and the length for a medium was perfect.
